THE New York Times is pimping out its journalists for cash. The Gray Lady — through its 3-year-old Knowledge Network, an adult education program — is offering on line, weeklong courses with op-ed columnists Nicholas Kristof, who will deal with sex trafficking, and Gail Collins, who will teach women’s liberation. The courses include a “live interactive Webcast,” three written lessons, and a message board where students can interact with their idols — all for $185. Wine writer Eric Asimov is offering a single session for $125, either online or in person, chardonnay not included.
